Problems solved by technology

[0005] In order to overcome the defects of the current two-component two-component polyurethane plastic runway materials in use, and the current problem of unsafe and environmentally friendly plastic runway materials, the present invention provides a single-component moisture-cured polyurethane plastic runway material and its preparation method. All components in the formula are safe and non-toxic, and there is no need for chemical metering, and no additives such as cross-linking agents and chain extenders are required. It can be cured by using air or moisture on the surface of the substrate to produce cross-linking and bonding. Simple operation, convenient construction, the laid plastic runway is non-toxic and harmless, all indicators meet the requirements of GB / T14833-1993, excellent water resistance and heat air aging resistance

Abstract

The invention discloses a one-component moisture curing-type polyurethane plastic racetrack material and its preparation method. The one-component moisture curing-type polyurethane plastic racetrack material is composed of the following raw materials (by weight): methyl diphenylene diisocyanate, 4,4'- dicyclohexylmethane diisocyanate, polyether polyol, hydroxyethyl dodecyl alcohol, dibutyl benzoate, dibutyltin dilaurate, caprolactam, triethanolamine oleate, polyethylene wax, dilauryl thiodipropionate, trimethylol propane, ethyl acetate, amino silicon oil, a packing, an anti-ageing agent and a promoter. In the formula, safe and nontoxic ingredients are used to prepare the material of the invention. When the material is in use, chemometry is not required, and there is no need to add a cross-linking agent and a chain extender, etc. The invention has advantages of simple operation and convenience in construction. The paved plastic racetrack is nontoxic and harmless and has excellent water resistance and hot air aging resistance.

Description

technical field [0001] The invention belongs to the technical field of light-weight ground decoration materials, and in particular relates to a single-component moisture-curing polyurethane plastic runway material and a preparation method thereof. Background technique [0002] With the development of the national fitness campaign, the requirements for sports facilities are also increasing. The plastic track began in the 1960s with the plastic horse racing track laid by the 3M company in the United States with polyurethane materials. Compared with cinder and sand and gravel fields, the plastic runway has the advantages of good elasticity, good shock absorption performance, wear resistance and anti-aging. No pollution to the environment, easy to clean and maintain. Since the 19th Olympic Games, the main track and auxiliary areas of the track and field venues in previous Olympic Games have been paved with plastic, and the plastic track has been internationally recognized as...
